php curl post request with headers
php curl get request
php curl post form data
php curl post array
php curl post body
php curl put json

I am trying to debug an http post the I am trying to send from list application. I have been able to send the correct post from php CURL which corectly interfaces with my drupal 7 website and uploads an image.

In order to get this to work in my lisp application I really need to see the content body of my http post I have been able to see the headers using a call like this:

curl_setopt($curl,   CURLOPT_STDERR, $fp);
curl_setopt($curl, CURLOPT_VERBOSE, 1);

and the headers look the same in my lisp application but I have been unable to examine the body of the post. I have searched online and other people have asked this question but no one posted a response.

The content type of my http post is:


I have also tried many http proxy debuging tools but they only ever the http GET to get my php page but never capture the get sent from server once the php code is executed.

EDIT: I have added a code snipet showing where I actually upload the image file.

// file
$file = array(
  'filesize' => filesize($filename),
  'filename' => basename($filename),
  'file' => base64_encode(file_get_contents($filename)),
  'uid' => $logged_user->user->uid,

$file = http_build_query($file);

// REST Server URL for file upload
$request_url = $services_url . '/file';

// cURL
$curl = curl_init($request_url);
curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-type: application/x-www-form-urlencoded'));
curl_setopt($curl,   CURLOPT_STDERR, $fp);
curl_setopt($curl, CURLOPT_VERBOSE, 1);
curl_setopt($curl, CURLOPT_POST, 1); // Do a regular HTTP POST
curl_setopt($curl, CURLOPT_POSTFIELDS, $file); // Set POST data
curl_setopt($curl, CURLOPT_HEADER, FALSE);  // Ask to not return Header
curl_setopt($curl, CURLOPT_COOKIE, "$cookie_session"); // use the previously saved session
curl_setopt($curl, CURLOPT_FAILONERROR, TRUE);
curl_setopt_array($curl, array(CURLINFO_HEADER_OUT => true) );
$response = curl_exec($curl);

CURLOPT_VERBOSE should actually show the details. If you're looking for the response body content, you can also use CURLOPT_RETURNTRANSFER, curl_exec() will then return the response body.

If you need to inspect the request body, CURLOPT_VERBOSE should give that to you but I'm not totally sure.

In any case, a good network sniffer should give you all the details transparently.


$curlOptions = array(
    CURLOPT_STDERR => $verbose = fopen('php://temp', 'rw+'),

$url = "";
$handle = curl_init($url);
curl_setopt_array($handle, $curlOptions);
$content = curl_exec($handle);
echo "Verbose information:\n", !rewind($verbose), stream_get_contents($verbose), "\n";
echo $content;

POSTing JSON Data With PHP cURL,​not- Sample JSON POST body to [single endpoint] /mmmr Pingback: How to use PHP curl GET and POST with JSON web services | p6abhu. The PHP cURL is a library used for making HTTP requests. In order to use PHP cURL, you must have installed and enabled libcurl module for PHP on your system. In this tutorial, you will learn how to POST JSON data with PHP cURL requests. Basically, there are 4 steps involved to complete a cURL request using PHP.

How To POST JSON Data with PHP cURL, The PHP cURL is a library used for making HTTP requests. In 'Content-Type: application/json', must be a POST request with properly json-encoded data in the body. How to make a get request to the api using cURL. The name of a callback function where the callback function takes two parameters. The first is the cURL resource, and the second is a string with the data to be read. Using this callback function, it becomes your responsibility to read the data. Return the number of bytes read. Return 0 to signal EOF.

If you're talking about viewing the response, if you add curl_setopt( $curl, CURLOPT_RETURNTRANSFER, true );, then the document returned by the request should be returned from your call to curl_exec.

If you're talking about viewing the postdata you are sending, well, you should be able to view that anyway since you're setting that in your PHP.

EDIT: Posting a file, eh? What is the content of $file? I'm guessing probably a call to file_get_contents()?

Try something like this:

$postdata = array( 'upload' => '@/path/to/upload/file.ext' );
curl_setopt( $curl, CURLOPT_POSTFIELDS, $postdata );

You can't just send the file, you still need a postdata array that assigns a key to that file (so you can access in PHP as $_FILES['upload']). Also, the @ tells cURL to load the contents of the specified file and send that instead of the string.

curl_setopt - Manual, CURLOPT_NOBODY, TRUE to exclude the body from the output. Proxy headers must be set with CURLOPT_PROXYHEADER to get used. CURLOPT_COOKIE, The contents of the "Cookie: " header to be used in the HTTP request. User will submit the form, as usual. In the form processing PHP, I use cURL to execute a POST transmission to a PHP script on the customer's server. The remote script would do a MySQL INSERT query into the customer's private database.

I think you're better off doing this with a proxy than in the PHP. I don't think it's possible to pull the raw POST data from the PHP CURL library.

A proxy should show you the request and response contents

Set the Content-Type of request to application/json using the CURLOPT_HTTPHEADER option.

By insisting on curl using chunked Transfer-Encoding, curl will send the POST "chunked" piece by piece in a special style that also sends the size for each such chunk as it goes along.

Sending POST form data with php CURL, Sending POST form data with php CURL. or to use GET instead of POST To make a simple HTTP POST with text/xml as content-type, do something like: CURLOPT_NOBODY: TRUE to exclude the body from the output.

The basic idea behind the cURL functions is that you initialize a cURL session using the curl_init(), then you can set all your options for the transfer via the curl_setopt(), then you can execute the session with the curl_exec() and then you finish off your session using the curl_close().
